Letters Patent No. 94,943, dated Sqnembe'r 2], 1869; antellated September 6,- 1869.

IMPROVED AXLE-BOX LID.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, Jonn Bnrsrow, of r the city of Detroit, and State of Michigan, have inventeda new I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing, with its construction and operation. y g

The nature of myinvention consists in providing a cap for oil-boxes which shall prevent tlienecesfsity of removing the cap byunscrewing, in order to apply the oil, and thereby save a large amount of time and trouble in the operation, by means of a slide with spring on the inside, to keep it in place, both when open and when shut. The slide extends below the cap, and may be struck up with packing and iron or hammer, in case it should become fast, so that it cannot be removed by means i of a gap in front of slide,

' made for-the purpose, or raising saidcap, ordinarily.

A smallknob is placed below said gap, to prevent the slide from being taken out of said ,cap, and thereby being lost; This slide is slightly tapering, being wider at top than at bottom, to prevent its falling through the aperture in the. capinto which the slide is placed.

- The centre of this cap is open, as shown, and the slide fills up said opening, to keep out dirt, 850.

To enable others to make and use my invention, I will proceed to describe itsconstruction and operation.

-I construct my box in any of the kliown forms, and apply thereto my cap, withslide, to be opened by means of gap in front or projection below, and to be retained in position by a spring on either or both sides, attached either to the cap or the slide itself. This cap may be of any size, thickness, or 1naterial,.and can be used on all boxes requiring frequently to be opened, with very great advantage.

What 1 claim as my invention, and desire to secure by Letters Patent, is;

A removable car-axle oil-box cap, having a central opening, closed by a tapering slide, withgap, stop, and projection underneath, the slide retained in any desired position by side spring or springs, substantially as set forth, and for the purpose described.

- JOHN BRISTOW.
